' l ly invention relates tol automobiles, ,and

has for its ob'jectto provide a new-and improved device of this'character in which the various ope'rationsvofy starting and'stoppin'g4may be' effected with greater facility and without the use ofcomplicated mechanism.

The invention consists in 'the construction described in theaccompanying specification and set forth in the claims.

In the drawin s, Figure 1 is a side elevation of an automobie containingmy invention. Fig. 2 v4is a similar view showing the `essential featuresof my invention.

in the drawings, a represents an automobile of conventional form havinga metal frame b, as is usual and well known.

c represents the rear or driving wheelLand d the usual front Wheel. Therear or driving wheel d is mounted upon an axle g. This axle is securedto the upright -end of a drop axle-bar e, which is mounted in bearings 2so I as to rock therein. c The rim h of the rear or ing-rod p to 'anoperating-lever'n, fulcrurned at o in the frame of the machine.

Q represents a semicircular rack-bar having teeth which are en aged by adog (not shown) mounted upon the operating-lever n. A pivotedoperating-handle ris connectedto this dog, as will be readilyunderstood.

Mounted in the frame of the machine adjacent the rear wheel is anoperatingpulley Z,

grooved on its circumference. `'lhis pulley is'suitably connected. to amotor in any wellknown manner. The particular type of motor', however,forms no part of my invention,

and therefore has not been illustrated. The pulley Zhas also a reducedortion l', the circumference of which is p ain. A rope or other flexibleconnection m connects the pulley lwith the rear Wheel, as shown. Mountedin the side bar of the frame is a brake-bar t',

having at the end adjacent the driving-wheel.

lever 'r pushed forward toward the front of the carriageit will, throu hthe connectin rod p, cause the drop axlear to swing bac ward away fromthe motor. This will result in the tightening' of the rope or flexiblecon- 'wheel and the carriage will move forward. When the operating-leveris in its middle or neutral position, .the driving-wheel will be in thepositionshowniin Fig. 1 and the flexible ment of the motor will not betransmitted to the driving-Wheel. quently remain standing. When it isdesired to reverse the movement of the carriage and run backward, theoperating-lever is 4pulled toward the rear of the carriage, asindicatedl in Fig. 2. This will swing. the axlewheel will move forwardintoI engagement with the reduced portion rZ ofthe driving-pulley. The'.pulley, whichis constantly rotating in the direction indicated by thearrow in Fig. 2, will cause the driving-wheel to be turned in a reverseddirection, asl indicated brake-bar and brake-shoe are ordinarily held bythe latch in the position indicated in Fig. 1. When it lis desired toapply the .brake7 the o erating-lever is moved first to the posithe rearwheel forward into engagement with the brake-shoe. lt will be understoodthat. beforethe operating-lever can be moved farther to the rear, so asto vbring the driving- Wheel into engagementwith the pulley tov'drivethe carriage backward the-brake'must bereleased. This is accomlished by depressing the foot-lever w and re easin the latch fu,

bar and brake-shoe forward against the force of the spring u. `When thewheel is again moved backward out of engagement lwith thedriving-pulley, the spring will cause the brake to move into itsnormahposition and the latchl v will, enter its recess to hold thebrake-bar in this normal position.

lt will be seen thatl l have provided an extion s own in Fig. 1 and'then pulled overto- ','ward'the rear of the carriage, so as tornovewhen the driving-wheel will pus the brakey vurgef'ltoward thedriving-wheel by a spring tu' It will be seen that when theoperatingnection m.

It will also be understood that by the use of the drop-axles I amenabled to use Wheels of much larger diameter and provide a greaterclearance between the carriage-body and the ground.
